Abstract

The utility model relates to an embedded methanol drip type calciner. In the main technical proposal, a methanol drip type calciner is directly embedded into the wall of a heating furnace; the high temperature of a quenching furnace has the function of insulating and heating the methanol drip type calciner, thereby eliminating the insulation layer and reducing the manufacturing cost; and simultaneously, the two sides of the methanol drip type calciner are respectively provided with an injection pipe which is used for injecting air for cleaning or injecting nitrogen for atomizing methanol, thereby improving the decomposition effect and enhancing the working efficiency.

Description

Embedded methanol dropping decomposition furnace

Technical field:

The utility model relates to a kind of methanol dropping decomposition furnace, and finger can be organized under the structure assembly reduction manufacturing cost in minimizing especially, also can promote the embedded methanol dropping decomposition furnace of process furnace work efficient simultaneously.

Background technology:

The patent of invention case that TaiWan, China No. 95104087 " methanol dropping decomposition furnace " is the applicant, this methanol dropping decomposition furnace 4, as shown in Figure 1, be to be provided with well heater 42 in the inside of a body of heater 41, be provided with thermal insulation layer 43 between well heater 42 and the body of heater 41, and in well heater 42, establish a decomposing gas stove 44, decomposing gas stove 44 extends to the body of heater outside with a drip tube 45, and can be with methyl alcohol by drip tube 45 injecting gas decomposing furnaces 44, and stretch into inside heating furnace with an output tube 46, one temperature measuring stick 47 stretches into decomposing gas stove 44 inside by the body of heater outside simultaneously, little by decomposing gas stove 44 internal spaces, cooperate the heating of well heater 42 again, make decomposing gas stove 44 inside reach desired high temperature, and methyl alcohol can be decomposed fully, form the carburizing gas of high carbon element, not only can improve the heat energy service efficiency, and propane more must not instil, more can avoid the generation of coal smoke, thereby promote the working efficiency of process furnace, this methanol dropping decomposition furnace 4 is arranged on the place, top of process furnace, and be and extraneous state of contact, therefore preventing under the prerequisite of heat energy dissipation, between well heater 42 and body of heater 41, establish, but the applicant thinks to still have and is improved part with thermal insulation layer 43, and should seek to improve the efficient of methanolysis, to allow whole efficiency more increase.

The utility model content:

Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, a kind of embedded methanol dropping decomposition furnace is provided, embed by methanol dropping decomposition furnace in the furnace wall of process furnace, and can reduce the setting of thermal insulation layer, to reduce manufacturing cost.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of embedded methanol dropping decomposition furnace, it comprises a body of heater, a well heater is established in this body of heater inside, this well heater outside is provided with protective tube, be the decomposing gas chamber between protective tube and the furnace wall, and one temperature measuring stick is stretched out outside the stove by the decomposing gas chamber, one output tube stretches into the inside of process furnace by the decomposing gas chamber, and a drip tube stretches into the decomposing gas chamber by the external world simultaneously; Be characterized in: described methanol dropping decomposition furnace directly is embedded the place, furnace wall at process furnace, and described body of heater protrudes from the outer dual side-edge of process furnace and establishes a gas injection tube respectively.

So,, come methanol dropping decomposition furnace is formed an effectiveness that is incubated and heats,, can reduce manufacturing cost to reduce the setting of thermal insulation layer with the high temperature that utilizes quenching furnance by methanol dropping decomposition furnace directly being embedded place, furnace wall at process furnace; Simultaneously be respectively equipped with injection tube in two sides, wherein an injection tube can inject air, with to carrying out cleaning operation in the stove; Another injection tube energy nitrogen injection decomposes effect to make the methyl alcohol atomizing improve.

Embodiment:

Effect for being easier to understand structure of the present utility model and reached cooperates graphic being described as follows now.

See also Fig. 2 and shown in Figure 3; the utility model is that methanol dropping decomposition furnace 1 directly is embedded 21 places, furnace wall at process furnace 2; this methanol dropping decomposition furnace 1 is established a well heater 12 in body of heater 11 inside; these well heater 12 outsides are provided with protective tube 13; it between protective tube 13 and the furnace wall decomposing gas chamber 14; and one temperature measuring stick 15 is stretched out outside the stove by decomposing gas chamber 14; and establish the injection tube 16 of a gas respectively in outer two sides that body of heater 11 protrudes from process furnace 2; and an output tube 17 is stretched into the inside of process furnace 2 by decomposing gas chamber 14; a drip tube 18 stretches into decomposing gas chamber 14 by the external world simultaneously, methyl alcohol can be injected body of heater inside by drip tube 18.

Methanol dropping decomposition furnace 1 of the present utility model is embedded 21 places, furnace wall at process furnace 2, and make its well heater 12, protective tube 13, decomposing gas chamber 14 all is positioned at 21 inside, furnace wall, being in one at process furnace 2 continues under the condition of high temperature of heating, relative furnace wall also can be a higher temperature, naturally do not need like applicant's preceding case generally between well heater 12 and furnace wall, thermal insulation layer to be set, and the setup fee that can reduce this thermal insulation layer is used, in addition, the dual side-edge that protrudes from 21 outsides, furnace wall is provided with a gas injection tube 16 more respectively, a gas injection tube 16 wherein can be for injecting air, and can form the cleaning effect that a brute force blows to inside by the air that injects, to keep the clean of inside, can avoid causing the reduction of usefulness because of dirt is dirty; But the gas injection tube 16 of opposite side is nitrogen injection then, by the injection of nitrogen, can make the methyl alcohol atomizing of injecting gas decomposition chamber 14, and can allow the decomposition of methyl alcohol more improve, make the heat energy service efficiency of process furnace better, can guarantee more that then process furnace 2 inside can not produce coal smoke.
